SAFETY MECHANISM FOR FIREARMS.

Application filed August 27, 1925. Serial No. 52,899.

To all whom it may concern: Straddling this flattened portion of thepost Be it known that I, LOUIS P. SMITH, a 6 is a yoke member 8 which isoperatively citizen of the United States of America, reconnected to thebarrel locking bolt 9. This siding at Ithaca, in the county of Tompkinsyoke 8 is retained in its operative position 60 and State of New York,have invented cerby means of the pin 10 which has the lattain new anduseful Improvementsin Safety erally projecting cylindrical head 11, asbest Mechanism for Firearms, of which the folshown in Fig. 2. The topand bottom tangs lowing is a specification. of the frame 5 are connebtedby the bolt 12.

This invention relates to new and useful In Fig. 3 there is shown indetail a push 10 improvements in safety mechanism for firebar whichincludes the elongated body porarms, tion 13 having the longitudinallyextending The primary object of the invention is the slot 14 formedintermediate its ends. The provision of safety mechanism for firearmsforward end of this push bar body 13 carries of the break-down type,wherein the moving a fork 15 having a laterally extending de 15 of thebarrel locking member to an unlocked clining arm 16 carried by one sidethereof osition will cause the trigger or triggers to which is providedwith a rearwardly bent e locked by the safety mechanism, which endportion 17 that terminates inwardly of mechanism will remain inactive orin its the outer ends 0f the side POItiOIlS Of the locked position, evenafter the barrel has fork 15 and is provided with a depending 20 beenclosed and locked, until manually relug 18 located in a plane extendingtransleased versely to the axis of the body portion of A further objectof the invention is the the push bar. provision of a novel form ofconnection be- By inspecting Fig. 1 it Wlll be seen that tween thebarrel lock actuating member and this push bar is arranged with the post6 reso 25 the trigger engaging and holding member. ceived within thefork 15 and with the rear- Other objects and advantages of the in-Wardly bent end 17 resting upon the cylinvention will be apparent duringthe course drical head 11 of the pin 10. The depending of the followingdescription. lug 18 is further illustrated as bearing In theaccompanying drawing forming a against the rear face of the head 11. The30 part of this specification and in which like slotted portion 14 ofthe push bar receives numerals are employed to designate like the tangbolt 12 and permits the said push parts throughout the same, bar to movein respect thereto. The rear end Figure 1 is a side elevational view ofthe of the body portion 13 of this push bar is safety mechanismembodying this invention provided with a longitudinally extendingproperly mounted within the frame portion finger 19 which forms theshoulders 20 on of a fire arm, this end of the said push bar.

Figure 2 isa transverse sectional View of In Figs. tand 5 there is showna spring the barrel lock actuating member with the member including'atapering body portion safety mechanism setting pin carried thereby 21having an elongated slot 22 formed there- 40 and shown in top plan, in,as best illustrated in Fig. 4. The rear Figure 3 is a detail plan viewof a push end 23 of this body portion 21 is bent upbar employed inconnection with the safety wardly and downwardly into an inverted mechaism, V-formation, which portion of the spring Fi 4 i t l i f a f tmember will be described in connection with 45 button retaining springwhich also functions I s functi n at a later point in the descriptooperat-ively connect the button with the 'tion. The forward end of thisspring mempush bar shown in Fig. 3, and her 21 is provided with anupturned flange Figure 5 1s an'end elevational view of the 24 which istransversely slotted at 25, see spring member shown in Fig. i. Fig. 5,and is provided with an inwardly 59 In the drawing, wherein for thepurpose turned lug 26 at its outer edge which overof illustration isshown a preferred embodilies the body portion 21 of the spring memmentof this invention, the numeral 5 desigber. nates the frame portion inits entirety which In Fig. 1 this spring member is illustrated hasjournaled in the upper portion thereof as having the finger 19 of thepush bar pro- 55 a post 6 flattened at its opposite sides, as jectinginto the slot 25 while the slot 22 redesignated by the numeral 7 in Fig.2. ceives the forked portion 27 of the safety button 28. This forkedportion 27 is provided with a laterally projecting pin 29 whichunderlies the body portion 21 of the spring member, as shown. It will beunderstood that this spring member, in bearing against the inner face ofthe upper tang of the gun frame 5 and the upper face of the pin 29, willretain the fork 27 within the slot 30 formed in the upper tang.

This upper tang is provided with a recess 31 which is intended toreceive a danger signal of any desired type which will be exposed whenthe safety button 28 is in the position illustrated in Fig. 1, i. e.,when the fork 27 is permitted to be arranged at the forward end of-theslot 30. The under face of this upper tang is provided with a seriesof-spaced notches 32 into which the inverted V-shaped end 23 of thespring member projeets for aiding in holding the spring memher, thesafety button 28,-and the push bar in either of two operative positions.This safety mechanism further includes an angular lever 33 whichispivoted to the lugs 34 carried by the lower tang of the gun frame. Theupstanding arm of this angular lever projects between the sides of thefork 27 while the opposite end portion is received within a cavity ornotch 35 formed inthe pivoted bolt 36 which is provided with a laterallyprojecting pin .37 that is intended to be moved into engagement with theupper edge 38 of the heel portions of the triggers '39 for preventingoperation of the triggers.

The operation of this safety mechanism may be described as follows Uponrotatingthe post 6 in a counter clockwise direction when viewed fromabove, the yoke 8 will be actuated for rotating the barrel locking bolt9 to release the barrel. This movement of the post 6 will cause thecylindrical head portion 11 of the pin 10 to move rearwardly in'an'arcuate path. This rearward movement of the head of the pin 10 willcause the push bar 13 to be moved longitudinally rearwardly of theframe, due

to the engagement of the head 11' with the depending lug 18 of the pushbar. This rearward movement of the push bar will cause the shoulders 20to engage the opposite sides of the upturned flange 24: of the springmember for moving this latter member rearwardly of the gun frame.Thisrearward movement of the spring member will cause the fork 27 andthe button 28 to travel rearwardly through the slot 30, which rearwardmovement will cause the lever 33 to pivot for rocking the bolt 36 uponits fulcrum for shifting the pin 37 into a position to engage thesurfaces 38 of the triggers 39. When the post 6 is returned to theposition illustrated in Figs. 1 and 2, the head 11 of the pin 10 willreturn to its truly laterally extending position, but will leave thepush bar and its into their shifting,

trigger-locking position. It will now be understood that the barrel islocked into its breech closing position and the safety mecha nism isstill functioning to retain the triggers 39 against movement. To unlockor release these triggers, the safety button 28 should be movedforwardly for causing the fork 27 to engage the forward end of the slot22 in the spring member for moving this latter member toward the post 6.Thismovement of the spring member will cause the push bar to be returnedto the position illustrated in Fig. 1. The angular lever 33 will also bepivoted for rocking the bolt 36 into the position illustrated in Fig. 1wherein the triggers 39 will be free to operate.

It is to be understood that the form ofthis invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
